BitTitan® now supports Modern Authentication for Office 365 endpoints used for Mailbox migrations. Modern Authentication provides a more secure authentication mechanism for registered applications to connect to Azure Active Directory and Office 365. For more information on Modern Authentication, see this page from Microsoft: How to authenticate an EWS application by using OAuth.

Prerequisites

A Global Administrator account with access to Azure Active Directory.

MigrationWiz® Mailbox project(s) created and ready for configuration.

The Global Administrator account must have Multi-Factor Authentication (MFA) disabled.

Under Redirect Uri, select Public Client (mobile & desktop) and set it to urn:ietf:wg:oauth:2.0:oob

Click Register.

Go back to App registrations.

Select the App you just created.

In the Overview, you will find a ClientId (aka Application) and Directory (Tenant) ID.

Copy both of these to another application, such as Notepad, for use later in this process.

Under the Manage menu, select Authentication.

Set the option Treat application as a public client to Yes. Note: This does not open public access; it indicates that the client is not capable of protecting the Open Authorization client secrets. A different authentication mechanism will be needed.

Run a Verify Credentials to confirm that MigrationWiz can connect using Modern Authentication. For specific steps, see How do I verify credentials?

Click on the item that was verified. There will be a message in the MigrationWiz Migration Information page that Modern Authentication is being used. Note: This message will show in the “Migration Errors” box; however, it is not an error. This is just a message confirming that Modern Authentication is now active and being used for connection.
